1. 用 sys 用户登录 Oracle 必须用sys登录；

2. 创建记录用户登录信息的表

CREATE TABLE LOG$INFORMATION
(
   ID        NUMBER(10),
   USERNAME VARCHAR2(30),
   LOGINTIME DATE,
   TERMINAL VARCHAR2(50),
   IPADRESS VARCHAR2(20),
   OSUSER    VARCHAR2(30),
   MACHINE   VARCHAR2(64),
   PROGRAM   VARCHAR2(64),
   SID       NUMBER,
   SERIAL#   NUMBER,
   AUSID     NUMBER
)

3. 创建一个 Sequence，作为登录信息的主键

CREATE SEQUENCE LOGIN_SEQ
minvalue 1
maxvalue 9999999999
start with 1
increment by 1
cache 20

4. 创建触发器，记录用户登录信息

CREATE OR REPLACE TRIGGER LOGIN_RECORD_TR
AFTER logon ON DATABASE
DECLARE
mtSession v$session%ROWTYPE;
CURSOR cSession(iiQuerySid IN NUMBER) IS
    SELECT * FROM v$session
       WHERE audsid = iiQuerySid;
BEGIN
OPEN cSession(userenv('SESSIONID'));
   FETCH cSession INTO mtSession;
      IF cSession%FOUND AND SYS_CONTEXT ('USERENV','IP_ADDRESS') IS NOT NULL THEN
         INSERT INTO log$information(
            id,
            username,
            logintime,
            terminal,
            ipadress,
            osuser,
            machine,
            program,
            sid,
            serial#,
            ausid
         ) VALUES(
            login_seq.nextval,
            USER,
            SYSDATE,
            mtSession.Terminal,
            SYS_CONTEXT ('USERENV','IP_ADDRESS'),
            mtSession.Osuser,
            mtSession.Machine,
            mtSession.Program,
            mtSession.Sid,
            mtSession.Serial#,
            userenv('SESSIONID')
         );
      END IF;
   CLOSE cSession;
EXCEPTION
   WHEN OTHERS THEN
     RAISE;
END;
